I wonder if either frame generation algorithm prioritizes real frames over fake ones? I have a 50" monitor that will only do 60hz at 4kUW with HDR. At absolute max settings at 4K I can't tell a difference with CP2077 as I'm pretty much locked at 60 anyway, either way feels smooth and I don't see any artifacting at all with DLSS3.5... Is it just not bothering to render extra frames if it's already delivering the max framerate my monitor is reporting?

In some circumstances in some games it would be worth rendering undisplayed frames if they were actually rendered, not fake frames as those aren't actually rendered.

The reason being that it would give you a fraction of a second faster notice of changes in the gameworld. Humans are capable of accurate recognition at 240+ FPS in ideal circumstances with a highly trained person. It has been tested (initially by the USA air force, maybe others since then). But for normal people playing normal games for fun, 60 FPS is fine. If you were playing competitively at a high enough level then rendering undisplayed frames would be of some use but once again only if they were real frames, frames that were actually rendered. Frame generation results in fake frames, frames that are not actually rendered.

If your monitor refresh rate is 60 FPS and your PC can reliably render 60+ FPS in a game and 60 FPS is fine (as it is for most games) then frame generation is at best useless to you. With it on you'll be seeing a mixture of real frames, frames that are actually rendered, and fake frames, frames that are generated and not rendered. It will not prioritise real over fake. The real frames will give you up to date information about the gameworld. The fake frames will not. You'd be better off turning frame generation off. Frame generation is only of any use if your PC can render frames fast enough for frame generation to not add too much extra lag but not fast enough to keep up with your monitor's refresh rate. Or if you want to inflate your framerate for advertising purposes for some reason.

Take Starfield for example. I regularly get around 120FPS. If I enable FMF it shows I'm getting around 260-270 in the AMD tool. However the framerate that is actually sent to my screen is only about 130. I did get a small improvement, but not really significant. (Do note that my monitors are capable of 144FPS and can "overclock" to 160FPS in game mode.)

Now while I did not get a very perceptible increase in actual FPS, what I did notice was that movement was a LOT smother. When taking quick turns and movements instead of getting a bit of micro-stutter, it was very smooth.

In 7 Days, I don't think I would see much benefit from FMF. I keep a similar FPS average as I do in Starfield, but I'm not currently noticing any stuttering outside of the loading on large buildings in populated areas. FMF isn't going to help with that at all.
